Brief summary

The purpose of the study is to investigate the addition of high frequency chest wall oscillation (HFCWO) therapy to the prescribed care regimen to support the diaphragm during airway clearance among post-COVID patients with COPD and chronic productive cough as a way to limit the advancement of pulmonary symptoms and need for critical services during recovery from COVID-19.

Detailed description

Thirty study participants in New York City who meet inclusion criteria will be recruited from Mount Sinai's COVID-19 Post-Recovery Center of Excellence and Respiratory Institute. Fifteen subjects (determined by the last digit of their medical record number) will receive a HFCWO device (AffloVest), digital thermometer, pulse oximeter, and spirometer at their home. Participants will be trained remotely to use the AffloVest and spirometer. In addition all subjects will be asked to complete a series of online mental health and respiratory symptom assessments via REDCap. A 15 patient control group meeting inclusion criteria will be recruited from the Mount Sinai COVID-19 Post-Recovery Center of Excellence and Respiratory Institute using the same screening process. This group will not receive the HFCWO intervention but will receive a digital thermometer, pulse oximeter, and spirometer at their home (with training via telehealth), asked to complete all REDCap and respiratory symptom assessments. Consent for both groups will be obtained by a Mount Sinai clinician-researcher. Study Duration Approximately 30 days plus 60 and 90-day check in Objectives To investigate the addition of HFCWO therapy to the prescribed care regimen to support the diaphragm during airway clearance among post-COVID patients with COPD and chronic productive cough as a way to limit the advancement of pulmonary symptoms and need for critical services during recovery from COVID-19.

Interventions

DEVICEHCFWO

The Afflovest device is a High Frequency Chest Wall Oscillation (HFCWO) device, a medical vest that uses vibrations to loosen and mobilize mucus in the lung secretions and help clear the airways.

OTHERStandard Care Plus Monitoring

Monitoring via home spirometry, pulse oximetry, temperature checks, telehealth check-in and patient-reported outcome assessments.

Design outcomes

Primary

MeasureTime frameDescription
Change in forced expiratory volume in one second (FEV1)Baseline and up to 90 DaysChange in forced expiratory volume in one second (FEV1) as compared to baseline, measured by home spirometer.
Change in Oxygen Saturation levelBaseline and up to 90 DaysChanges in oxygen saturation from baseline as measured by pulse oximeter. Normal oxygen range is 95 to 100 percent and low oxygen range is under 90 percent.
Change in Presence of FeverBaseline and up to 90 DaysChanges in basal temperature as measured by digital thermometer. Fever is indicated at 100.4 F (38 C) or higher.

Secondary

MeasureTime frameDescription
Change in Mental health screening via General Anxiety Disorder-7 (GAD-7)Baseline and up to 90 DaysThe General Anxiety Disorder 7-item questionnaire (GAD-7) is a 7-item questionnaire that asks user to rank how often they have been bothered by seven problems over the past two weeks from 0 (not at all) to 3 (nearly every day). Full scale from 0-21, with higher score indicating more symptoms.
Change in Presence of pneumonia symptoms via Community Acquired Pneumonia (CAP) Symptom QuestionnaireBaseline and up to 90 DaysCAP Symptom Questionnaire records how much the patient rated the bothersomeness of the symptom. Each item is scored as 0 (Patient did not have this symptom), 1 (Not at All) to 5 (Extremely). Full range scale from 0 to 90, higher score indicating patient experiencing more frequent or more severe symptoms.
AffloVest Usage90 DaysAmount of time used per week in minutes
Change in COVID Symptom ChecklistBaseline and up to 90 DaysEight questions that are specific to recent literature describing patients' experiences of symptoms during COVID. They are rated on a frequency scale from never to always, using a 1-4 point scale. Full scale range from 8 to 32, with higher scores indicating more frequent symptoms.
Change in Quality of life via Quality of Life Questionnaire-Respiratory (QOL-B)Baseline and up to 90 DaysThe QOL-B is a disease-specific questionnaire that measures symptoms, functioning, and health-related quality of life relevant to patients with bronchiectasis. Scores are generated from 37 items that fall on 8 domains: Physical Functioning, Role Functioning, Vitality, Emotional Functioning, Social Functioning, Treatment Burden, Health Perceptions, and Respiratory Symptoms. All subscales and the full range scale are standardized to score from 0 to 100, with higher scores indicating better enjoyment and satisfaction with specific life domains.
Change in Mental health screening via Personal Health Questionnaire Depression Scale (PHQ-8)Baseline and up to 90 DaysThe PHQ-8 is the depression module, which scores each of the eight DSM-IV criteria as 0 (not at all) to 3 (nearly every day). Full scale from 0-24, with higher score indicating more severe symptoms.
